Jyn Erso (Felicity Jones) has never been one to follow rules. She's been on her own since the age of 15, surviving in the galactic underworld by cultivating skills in both fighting and cunning.

When Jyn is arrested by the Rebel Alliance, she is asked by Mon Mothma (Genevieve O'Reilly) to retrieve information about the Death Star - a nearly constructed weapon with the power to destroy an entire planet. If the Death Star's construction is completed, the Empire will become unstoppable.

It's up to Jyn, Cassian Andor (Diego Luna), Bodhi Rook (Riz Ahmed), and their pragmatic droid K-2SO (Alan Tudyk) to form the Rogue One squadron and help bring peace to the galaxy by stealing a technical readout of the Death Star. They eventually join forces with assassin Baze Malbus (Jiang Wen) and his spiritual partner Chirrut Imwe (Donnie Yen). They also meet Clone Wars veteran Saw Gerrera (Forest Whitaker).

They're up against some stiff competition. Orson Krennic (Ben Mendelsohn) is an Imperial military director who will stop at nothing to see the Death Star's completion. All while Darth Vader (James Earl Jones) maintains a watchful eye on the weapon.
